To aZZ whom it may concern.-

Be it known that I, THOMAS J. PRICE, a citizen of the United States, anda resident of Danville, Montour county, Pennsylvania, have inventedcertain Improvements in Feeding Devices for Skelp-Wlills, &c., of whichthe following is a specification.

The object of my invention is to provide a simple but efficient devicefor facilitating the handling of metal bars or plates in certainrolling-mill operations-for instance, in taking a bar or plate from atrain of finishingrolls and feeding it forward to apair of shears orother machine in which said bar or plate is subjected to subsequenttreatment.

The invention comprises a pair of feedrolls, one of which is positivelydriven, the other being provided with mechanism whereby it may be movedtoward or from said positively-driven roll, all as fully describedhereinafter.

In the accompanying drawings, Figure l is a plan view of a feedingdevice constructed in accordance with my invention. Fig. 2 is a frontview of the same, looking in the direction of the arrow l, Fig. l; andFig. 3 is an end view, on a larger scale, looking in the direction ofthe arrow 2, Fig. l. j

A is a bed-plate, upon which are suitable bearings d for the shaft. b ofa roll B, said shaft being provided with a pulley D for receiving adriving-belt from a pulley on any adjacent counter-shaft, that portionof the shaft b beyond the pulley being adapted to a bearing a.

. On the bed-plate A, adjacent to the bearings d, are other bearings dfor a rock-shaft F, which carries a pair of arms f, to bearings at theouter ends of whichis adapted the shaft or spindle of a roll G,preferably considerably less in diameter than the roll B. The shaft Fprojects in one direction considerably be yond the bearings d, and isadapted to abearing g, near the base of a standard I-I, mounted on thebase-plate A, the outer end of said shaft F being provided with aspur-wheel h, which meshes with a spur-pinion on a shaft J, the latterturning in a bearing lo at the upper end of the standard H, and in asimilar baring la at the upper end of alike standard H', mounted uponthe bed-plate A, adjacent to the standard H.

The outer end of the shaft .I is provided with a hand-wheel K, wherebysaid shaft can be readily turned in either direction, such movementbeing transmitted through the spur-gearing to the shaft F, so thatarocking movement can be imparted to the latter shaft, and its arms fthereby vibrated, so as to carry the roll G toward and from the roll B.The latter roll rotates continuously, and during the rolling of the baror plate by the train of rolls the roll G occupies aposition awayfromthe roll B, as shown, for instance, by dotted lines in Fig. 3.

The feeding device forming the subject of my invention is, bypreference, so located in respect to the rolls that as the bar or plateleaves the finishing-pass the end of the same will be projected over theroll B, and the hand-wheel K is then manipulated so as to swing therock-shaft F and cause the roll G to move over and toward the roll B,this movement continuing until the bar or plate is firmly grippedbetween the rolls B and G, and is consequently fed forward, owing to therotation of said roll B, the parts preserving this relation to eachother until the feeding of the bar or strip has been completed,whereupon the roll G is again moved away from the roll B until anotherbar or strip has to be acted upon.

The bed-plate A is preferably sunken beneath the floor of the mill tosuch an extent that the roll B proj ectsbut slightly above thefloor-line of the mill, as shown, for instance, in Fig. 3.

Having thus described my invention, I claim and desire to secure byLetters Patentl. The combination of the lower roll and means forrotating the same with the upper roll, a rock-shaft having arms carryingsaid roll, a spur-wheel secured to said rock-shaft, a spur-pinionengaging with said wheel, and a shaft carrying said pinion and providedwith a hand-wheel, substantially as specified.

2. The combination of the lower roll and means for rotating the same,the upper roll, a rock-shaft having yarms carrying said upper roll, aspur-wheel on said rook-shaft, a pin- ICO ion engaging with saidspur-Wheel, a, pinionshaft having a hand-Wheel, and a bed-plate havin@at one end bearinvs foithe rock-shaft V Y and t-le shaft of Jhe drivenroll and at the THOMAS PRICE "Witnesses:
